BACKGROUND: Advances in anti-lymphoma therapy prolong overall survival, making late adverse effects, like doxorubicin-related cardiotoxicity, an even more important clinical issue. The effectiveness of cardioprotective strategies with close monitoring, angiotensin-converting enzyme inhibitors and/or β-blockers as well as liposomal doxorubicin are still unconfirmed in clinical practice.
METHODS: This study evaluated the role of a primary cardioprotection strategy in preventing cardiovascular mortality and heart failure occurrence in non-Hodgkin lymphoma (NHL) patients with a high risk of anthracycline cardiotoxicity. Thirty-five NHL patients were subjected prospectively to ramipril and/or bisoprolol at NHL diagnosis, before implementing doxorubicin-containing regimens. Additionally, patients with a diagnosis of asymptomatic/mild heart failure received the liposomal form of doxorubicin. The clinical outcome and frequency of all serious cardiac events were compared with the results in a historical cohort of 62 high-risk cases treated without primary cardioprotection.
RESULTS: NHL patients with a primary cardioprotection strategy did not experience cardiovascular deaths in contrast to the retrospective control group where cardiovascular mortality was 14.5% at 3 years (p < 0.05). Primary cardioprotection also decreased the frequency of new cardiotoxicity-related clinical symptoms (2.8 vs. 24.1%; p < 0.05) and prevented the occurrence of cardiac systolic dysfunction (0 vs. 8.5%, respectively; p < 0.05). Although the study was not planned to detect any survival benefit, it demonstrated a trend towards increased response rates (complete response 82 vs. 67%; p not significant) and prolonged survival (projected 5-year overall survival 74 vs. 60%; p < 0.05) for patients treated with primary cardioprotection.
CONCLUSIONS: A primary personalized cardioprotection strategy decreases the number of cardiac deaths and may potentially prolong overall survival in NHL patients with increased risk of anthracycline cardiotoxicity.
